  • Publication number: 20060062371
    Abstract: A method includes establishing a first communication link between a telephone having a plurality of input/output functions and a target device. An alternate access device is associated with the telephone. At least one of the input/output functions is transferred to the alternate access device. A second communication link is established between the target device and the alternate access device.

  • Patent number: 4591841
    Abstract: A long range optical pointing apparatus (10) is disclosed which can locate a spot (24) on a video screen (16) from a position several feet away from the screen. An optical pointer unit (11) focuses a portion of the raster lines traced over the video screen during one frame onto a photodetector (28), and provides an output pulse when a raster line is focused upon and detected by the photodetector. The detected raster line pulses are provided to a processing unit (13) which also receives the vertical and horizontal deflection signals from the video terminal (15). The processing circuitry (13) averages the positions of the group of raster line portions detected by the optical pointer unit to provide an averaged vertical and horizontal position for the area of the screen at which the pointer (11) is directed.
